Bolsonaro has been arrested after authorities concluded he posed a definite escape threat while under house arrest.
The one-time leader was sentenced of planning a military coup in the ninth month and given more than a 27-year term in incarceration, but he continued under confinement pending legal challenges.
High Court Judge Alexandre de Moraes said the decision to arrest the septuagenarian politician was a preventative measure after "new facts" were revealed.
This encompassed seeking to disable his tracking device and a invitation to a demonstration that could enable a chance to flee".
Judicial Records Show Flight Fears
In a filing authorising the arrest, the judge said intelligence from the facility tracking Bolsonaro's house arrest suggested the former leader's plan to remove the surveillance device to ensure success in his escape.
This, it said, would be assisted by the chaos caused by the gathering called by his offspring.
His offspring, his son Flávio, who serves as a legislator, called for a assembly of his followers near his father's house to take place on the weekend.
Flávio Bolsonaro wrote on social media on the previous day: Will you battle for your nation, or watch it all from your mobile device there on your sofa? I call on you to battle with us."
He said the gathering would be so supporters could seek divine intervention for his well-being and for the reestablishment of democratic governance in our country."
Embassy Asylum Concerns
Part of the judge's determination was the possibility of the former president's transfer to diplomatic missions near the residence, considering that the inquiries revealed a background of arranging to seek refuge through a diplomatic representation", a declaration said.
The court filing emphasizes that the United States embassy in the capital, Brazil's capital, is situated around 13km from his dwelling.
International Reactions
The former president's legal troubles have provoked anger from fellow populist conservative US President Trump, causing him to implement a half-rate duty on Brazilian product imports.
The former president is being detained in a national police facility in Brasilia and will have a imprisonment assessment on Sunday.
Recent Legal Requests
It was only on the previous day that the former president's lawyers asked the Top Court to permit him to serve his whole jail sentence under home confinement, with digital surveillance.
They also asked that Bolsonaro be authorized to exit his dwelling for healthcare, saying he demanded frequent medical attention for respiratory ailments and other ailments.
Details of Guilty Verdict
Bolsonaro was found guilty of heading a plot aimed at keeping him in power after he lost the presidential race to his left-wing rival, Luiz Inácio Lula da Silva.
Top judicial officials said that he was aware of a plan which involved plans to murder the current president and his vice-presidential running mate, Geraldo Alckmin, and to arrest and execute Alexandre de Moraes - the Supreme Court justice who has been presiding over Bolsonaro's trial.
The plot was stopped because it couldn't obtain the backing of the military leaders. Lula was inaugurated without issue on the first day of 2023.
But a week later, on the eighth of January, many Bolsonaro supporters invaded and destroyed government buildings in the federal district, the capital city.
The security forces stepped in and around 1,500 people were detained.
The magistrates found that the demonstrators had been incited by Bolsonaro whose strategy, they said, was for the national armed forces to step in, restore order and return him to office.
At the period, the legal team called the 27 years and three months sentence extremely harsh.
He was also barred from seeking elected position until twenty-sixty - a decade minus two years after the completion of his term.
The one-time head of state called the court case a political persecution and said it was aimed at blocking him running in the 2026 presidential election.
